Llyn Coed Y Dinas is a splendid example of the modern practice in nature conservation of new habitat creation. The 8ha (20 acre) reserve is more than half occupied by the lake. This fills the gravel pit from which material was taken for construction of the Welshpool by-pass. The new wetland has proved a great attraction to wildlife.

Early arrivals on the water included a large flock of Canada Geese. These descendants of escapees from 18th Century wildfowl collections now pose something of a problem for nature reserve managers. But Llyn Coed y Dinas has been equally successful in attracting more unusual species. You cannot miss the activity at the Sand Martin Cliff, overlooked from the magnificent information hide and you will have to look much more carefully to spot the Little-Ringed Plover, which is well camouflaged against the mud and gravel background of the lake margin.

In the winter the lake becomes a wildfowl roost. Resident ducks such as Mallard and Tufted Duck are joined by Wigeon and the Mute Swans are met by Whooper Swans from the Arctic.

Llyn Coed Y Dinas is found at grid reference SJ 223052 and is clearly visible at the South End of the Welshpool by-pass. Park in the reserve car park.
